Bangor is a suburb in southern Sydney, in the state of New South Wales, Australia.

To avoid confusion with Bangor in Tasmania, the Postmaster General's Office changed the suburb name to Menai in 1910.

[2] As part of the modern development of Bangor, the streets were all named with an Aboriginal theme.

U-Go Mobility buses (routes 961 and 962) connect Bangor to Menai, Illawong, Alfords Point, Barden Ridge, Padstow, Bankstown, Sutherland, Kirrawee, Gymea and Miranda.

The Bangor Tigers Junior AFL team uses fields at Barden Ridge oval as its home ground.

The nearby Woronora and Georges rivers and extensive bush areas are popular with the locals and offer a variety of outdoor activities including bush walking, rock climbing/bouldering, mountain bike riding, boating, canoeing, kayaking, rowing and fishing.

A larger council run swimming complex and leisure centre operates at Sutherland.
